数据库中表名是：book,数据库表名不区分大小写的

之后我在hibernate 使用book， 

 

String sql="from book";         Query query=session.createQuery(sql);         List
     
       books=query.list();         for(Book book1:books)         {             System.out.println(book1.getName()+book1.getAuthor()+book1.getPrice()+book1.getId());         }
     

 报错：

Exception in thread "main" org.hibernate.hql.ast.QuerySyntaxException: book is not mapped [from book]

之后检查map 配置,book mapping 后是Book，将book->Book就好用了

 

<hibernate-mapping>

<class name="data.Book" table="book" catalog="study">

<id name="id" type="java.lang.Integer">

<column name="id" />
